The communications protocol SIP (Session Initiation Protocol) not only enables VoIP, but also other forms of realtime communications over the Internet. The beauty of this protocol is that it facilitates “global connectivity:” everyone reachable anywhere, at anytime. The true vision behind SIP was to bring the global business community together for collaboration, to improve productivity and generally help everyone work smarter, together.
I see global connectivity starting to happen in three steps: first, the adoption of SIP trunking, a technology that rapidly reduces communications costs by eliminating redundancies and making a connection between VoIP and the traditional telephony network (PSTN). The next step is allowing remote workers to utilize their corporate VoIP, IM etc. by accessing these features from anywhere, as long as there is access to an Internet connection. Last, this revolution toward global connectivity will happen as enterprises communicate with each other, freely and in real time over the Internet. And in doing so they are choosing the most appropriate form of communications for each situation.
SIP Trunking: An Immediate Impact on Communications Costs
A SIP trunk is the use of SIP to set up communications between an enterprise IP-PBX and a service provider where voice becomes just another application over the Internet. Unlike in traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, a SIP trunk is a logical connection from one point to another over an IP connection, like the public Internet.
The emergence of service providers offering SIP trunks to enterprises means that enterprises can outsource their PSTN connectivity to a third party – the service provider. All calls including long distance calls are carried over the Internet and the break out point to the PSTN is as close as possible to the party you are trying to reach. The call is passed over the PSTN from that breakout point to its final destination. For companies doing business globally on a regular basis, this can have a significant impact on long distance communications costs.
The most immediate way SIP trunks reduce telephony costs is that they make it unnecessary to purchase BRIs (Basic Rate Interfaces), PRIs (Primary Rate Interfaces) and local PSTN gateways. SIP trunks also produce long-term savings by supporting business growth. Using IP, there is typically excess bandwidth already included in the Internet connection, making it unnecessary to purchase additional capacity. There is often more than enough bandwidth to handle VoIP calls.
There are a number of important issues to touch on regarding SIP trunks, including security, infrastructure needs, the various ITSP service plans etc. Join Ingate and leading IP-PBX vendors, ITSPs and other industry influencers at the INTERNET TELEPHONY Conference & Expo in Los Angeles Sept. 10-11, for “SIP Trunking: Everything You Need to Know,” a series of educational seminars that are free to conference attendees.
